List of the Best Games for the Sega Genesis. These are not all the games, but they are the best as voted on by gamers. Sega Genesis was the second console released in the United States by the Sega Corporation. It was meant as a rival for the popular Super Nintendo and offered 16 bit entertainment. The Genesis had multiple successes throughout it's life span, but the most popular would have to be Sonic the Hedgehog, which was the Mario of Sega. This is not to say that other games like Altered Beast, NBA Jam and of course, Mortal Kombat, were not huge games as well. (Every gamer can tell you that Mortal Kombat on the Genesis was a much better version if only for the fact that the characters bleed instead of sweated.)Since this is the greatest games for the Sega Genesis, vote up your favorites and add your own if they aren't on the list.
